Fundamentals of C and NET Exception Handling Exception handling in C is used to manage and respond to exceptions or errors that occur during the execution of a program It includes try block where the code that might throw an exception is placed catch block where the code that handles the exception is placed finally block where the code that is executed whether an exception is thrown or not is placed Operators and Type Conversion Operators in C are symbols that perform operations on variables and values Type conversion is the process of converting one data type to another It can be Implicit automatically converting small data types to large data types Explicit manually converting large data types to small data types using casts Debugging and Good Program Practices Debugging is the process of finding and fixing bugs or errors in a program Good program practices include Writing clear and concise code Including comments and documentation Using version control Regularly testing and debugging code Integral Numbers in C Ranges and Bytes Integral numbers in C are whole numbers such as int long and byte The range of these numbers depends on the number of bytes used to store them Real Numbers in C float double and decimal Real numbers in C are numbers with decimal points such as float double and decimal The precision of these numbers depends on the number of bits used to store them Object Browser in Visual Studio Exploring Classes The Object Browser in Visual Studio is a tool for exploring the classes interfaces and namespaces in a NET application Formatting Strings in C Placeholder and Arguments strings in a type safe and efficient way Type Conversion in C Implicit Explicit and Casting Formatting strings in C using placeholders and arguments allows you to insert values into Type conversion in C can be implicit explicit or done through casting Knowing when to use each method is important for avoiding errors and ensuring the correct conversion of values The var keyword in C allows you to declare variables without explicitly specifying the type Var Keyword in C for Easier Declarations making it easier to write and maintain code Character and Boolean Data Types represents a boolean value true or false Byte Short Integer Long and Float s Capacities The char data type in C represents a single Unicode character while the bool data type The range and capacity of each integral number data type differ with byte being the smallest and long being the largest Floats in C have a precision of 7 decimal digits Overflow in C Checked and Unchecked Keywords The checked and unchecked keywords in C control whether arithmetic operations result in overflow errors or wraparound Scope of Variables in C C Primitive Data Types Non Primitive Data Types interfaces Control Structures and Loops The scope of a variable in C is the region of code where the variable can be accessed Understanding variable scope is important for writing clear and maintainable code Primitive data types in C are predefined data types such as int double and char Non primitive data types in C are user defined data types such as classes structs and Control structures and loops in C provide a way to make decisions and repeat actions based on certain conditions Examples include if else statements switch case statements and for and while loops Types Primitive and Non Primitive In C there are two types of data types primitive and non primitive Primitive data types are predefined while non primitive data types are user defined Variables Constants and Scopes Variables constants and scopes in C provide a way to store and access values and control access to code Understanding these concepts is essential for writing clean efficient and maintainable code Operators in C Operators in C are symbols that perform operations on variables and values They can be arithmetic relational logical or assignment operators Understanding the different types of operators and when to use them is important for writing efficient and error free code
